Pros: Ease of use, auto duplex, extensive image-handling options.
Cons: A little noisy, no fax.

I've had this for 9 months, attached to an iMac in a home office. The print copy is excellent, speed is very good, ease of use is excellent. The only thing missing is fax, but that's a small loss, since there are many web options.

The MP600 worked exactly as advertised out of the box. Ink cartridges are a bit expensive, and it uses 5 of them - small black, large black, small yellow, magenta and cyan. Does very good picture printing (via iPhoto), but pix need to dry for a while before handling.

Paper handling has been very good (although input tray could be bigger.) Have printed lots of duplex, 4x6 pix and envelopes with no paper jams.
